But after a series of back-and-forth statements, the former bassist and vocalist has said he’s no longer negotiating over the opportunity.

Cetera says: “Every idea or suggestion I offered about how it could work musically was either rejected or changed by the show’s producers.

“While I sent those same emails to the group, the only reply I ever received back from them was a very snarky ‘Take a chill pill, dude!’ Really?”

He adds: “At this point in my life I don’t care to reintroduce the negativity, misplaced egos and petty jealousies I left behind years ago.”

Cetera admits he’s disappointed with the outcome, but says: “There comes a time when you need to make a decision based on what’s best for you without worrying about the consequences – and this is that time.”
